Leather processing device

Abstract

The invention relates to the field of leather processing, in particular to a leather processing device. The leather processing device comprises a main frame body mechanism; the main frame body mechanism comprises a solution box, water adding ports, bottom brackets, a bottom shell, a cover plate, water discharging ports, a water discharging pipe and motor frames; the side wall of the upper port ofthe solution box is hermetically connected with a plurality of water adding ports; the lower side panel of the solution box is vertically connected with a plurality of bottom brackets; the upper portof the bottom shell is welded with the cover plate; the cover plate and the outer side wall of the solution box are vertically welded; the lower side panel of the solution box is hermetically connected with a plurality of water discharging ports; the water discharging ports are hermetically connected with the water discharging pipe; and one end, far away from the water discharging ports, of the water discharging pipe passes through the bottom shell and is arranged on the outer side of the bottom shell. The leather processing device can increase the number of the original leather which can perform unhairing processing simultaneously, is convenient to change, completely stirs a water body, enables the original leather to be completely contacted with lytic enzyme and increases the enzymolysisspeed.

Description

technical field [0001] The invention relates to the field of leather processing, in particular to a leather processing device. Background technique [0002] The leather processing method is a method of processing animal skins into mature skins for making leather products. Raw animal skin not only contains oil and hair fiber, but also hardens after drying. Therefore, in order to turn animal skin into leather that can be used by people, it must first be scraped and degreased, depilated, limed, delimed, and softened. , pickling and other preparatory processes, and then the bare hide is tanned with tannic acid. During the tanning process, tannic acid not only replaces the moisture in the raw hide, but also combines with the collagen fibers of the raw hide to become a heat-resistant, hydrolysis-resistant, and anti-microbial leather. [0003] During the processing of animal-made leather, the depilation process in the raw hide processing process is generally completed by using bi...

Problems solved by technology

[0003] During the processing of animal-made leather, the depilation process in the raw hide processing process is generally completed by using biological enzymes to enzymolyze animal hair, and most of the devices used in the enzymatic unhairing process fix the raw hide on the net, and then soak it In the solution, the fan blades driven by the motor in the solution tank are used to agitate the water body to increase the speed of enzymatic hydrolysis for depilation. The reference application number is: 201710299501.8 "an animal fur depilation device for leather manufacturing". However, this method can only process a small amount of raw hide at a time. The total length of the raw hide is relatively long, and the fur dissolution method of the chemical reagent used will completely dissolve the fur. Not only can it not be repeated. Utilization, multiple processes of filtration and purification are required when the waste liquid is discharged. In addition, the motor needs to be turned on and off repeatedly during hair removal, resulting in increased energy consumption, and the complex combined structure can only make a single raw hide hair removal, cost-effective low, there are many problems, so the present invention provides a leather processing device to solve the above problems
